Leukemia, a condition characterized by the abnormal proliferation of blood cells, poses significant challenges in cancer treatment. Thymoquinone (TQ), a bioactive compound derived from black seed, has demonstrated anticancer properties, including telomerase inhibition and the induction of apoptosis. However, TQ's poor solubility and limited bioavailability hinder its clinical application. This study explored the use of Sulfobutylether-β-cyclodextrin (SBE-β-CD), a cyclodextrin derivative, to enhance the solubility and stability of TQ for leukemia treatment. SBE-β-CD offers low hemolytic activity and has been successfully employed in controlled drug release systems. The study investigated the formation of inclusion complexes between TQ and SBE-β-CD and evaluated their effects on leukemia cell growth and telomerase activity. The results indicated that the TQ/SBE-β-CD complex exhibited improved solubility and enhanced cytotoxic effects against K-562 leukemia cells compared to TQ alone, suggesting the potential of SBE-β-CD as a drug delivery system for TQ. The annexin V-FITC assay demonstrated increased apoptosis, while the qPCR quantification assay revealed reduced telomerase activity in leukemia cells treated with TQ/SBE-β-CD, supporting its anti-leukemic potential. The molecular docking analysis indicated a strong binding affinity between TQ and telomerase. However, further research is needed to optimize the apoptotic effects and minimize necrosis induction. In conclusion, TQ/SBE-β-CD shows promise as a novel strategy for leukemia treatment by inhibiting telomerase and enhancing the cytotoxic effects of TQ, offering a potential solution to overcome the limitations of TQ's poor solubility and bioavailability.

Chronic myeloid leukemia (CML), a myeloproliferative neoplasm, is characterized by the fusion gene, which results in constitutive tyrosine kinase activity. While tyrosine kinase inhibitors (TKIs) have significantly improved CML outcomes, resistance and the persistence of leukemic stem cells remain major clinical challenges. Curcumin, a natural polyphenol derived from , has demonstrated potential anticancer properties.

Background: Patients with acute myeloid leukemia (AML) are often older, which brings challenges of endurance and persistent efficacy of autologous chimeric antigen receptor (CAR)-T cell therapies. Allogenic CAR-natural killer (NK) cell therapies may offer reduced toxicities and enhanced anti-leukemic potential against AML. CD33 CAR-NK cells have been investigated for AML therapy.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) provides a curative potential for high-risk patients with leukemia following first-line therapies, driven by potent immune cell-dependent anti-tumour activities. Although deep remission can be achieved, many patients relapse after allo-HSCT, and further treatment options are scarce. Given the potent immune cell-mediated anti-leukemic effects of allo-HSCT, adoptive cellular therapies (ACTs) have been explored as an adjunctive therapy to enhance the efficacy of allo-HSCT or to treat patients who relapse after allo-HSCT.

Introduction: Leukemia and radiation-induced liver toxicity are significant health challenges requiring effective therapeutic strategies. This study aimed to evaluate the therapeutic efficacy and radiosensitizing effects of Diosgenin-loaded silver nanoparticles (Dio-AgNPs) in ENU-induced leukemic mice, with a focus on their dual role in mitigating leukemia progression and γ-irradiation-induced hepatotoxicity.
Methods: Dio-AgNPs were synthesized and characterized using TEM, UV-Vis spectroscopy, FT-IR spectroscopy, and encapsulation efficiency analysis.
Unlabelled: Patients with myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) with high-risk features including mutations and deletions have poor outcomes due to lack of effective therapies. The atypical chemokine surface receptor C-C motif chemokine receptor-like 2 (CCRL2) is overexpressed in MDS and secondary AML (sAML) compared to healthy hematopoietic cells and we recently found that -mutated MDS/AML and AML with erythroid features express the highest levels of this receptor across MDS/AML subtypes. To illustrate the therapeutic potential of CCRL2 as a therapeutic target, we developed an anti-CCRL2 antibody-drug conjugate (ADC) by conjugating an anti-CCRL2 antibody with the cytotoxic drug pyrrolobenzodiazepine (PBD), which causes DNA double-strand breaks leading to cancer cell death.
